well for me is hard i took piano lesson and my teacher always want us to perform so since I'm not fast in reading notes its hard for me.. but if u know how to play guitar then piano will be easy for u..

it not hard to learn the piano with a lot of pratices but learning how to read music is hard... took me at about 2 years to actually read music without writing the scores out ... and play at the same time.... it very easy to remember the music ... well form my opinion... but have to say if you good at piano you will have good typing skills LOL
